The correct answer is B. Carbon-14 has more neutrons than carbon-12.Carbon-14 and carbon-12 are both isotopes of the element carbon, which means they have the same number of protons but different numbers of neutrons.The atomic number of carbon is 6, which means it has 6 protons. The difference between carbon-14 and carbon-12 is the number of neutrons in the nucleus.Carbon-12 has 6 neutrons, while carbon-14 has 8 neutrons. Therefore, carbon-14 has more neutrons than carbon-12.The other options are incorrect:A. Carbon-14 does not have fewer protons than carbon-12. Both isotopes have 6 protons.C. Carbon-14 does not have fewer neutrons than carbon-12. Carbon-14 has more neutrons than carbon-12.D. Carbon-14 does not have more protons than carbon-12. Both isotopes have the same number of protons.In summary, the key difference between carbon-14 and carbon-12 is the number of neutrons in the nucleus, with carbon-14 having more neutrons than carbon-12.
